JavaScript JavaScript Array Iteration Methods Array Iteration Practice forEach()

Can Anyone help me

Using forEach, iterate over the numbers array and multiply each number by 10, storing these new numbers in the times10 array.

app.js
const numbers = [1,2,3,4,5,6,7,8,9,10];
let times10 = [];
numbers.forEach(function(number) {
  times10[number] = number * 10;
});
// times10 should be: [10,20,30,40,50,60,70,80,90,100]
// Write your code below

Use the .push method to insert the values calculated into the time10 array.

const numbers = [1,2,3,4,5,6,7,8,9,10];
let times10 = [];
numbers.forEach(function(number) {
  times10.push(number * 10);
});
// times10 should be: [10,20,30,40,50,60,70,80,90,100]
// Write your code below

const numbers = [1,2,3,4,5,6,7,8,9,10];
let times5 = [];
numbers.forEach(function(number) {
  times5.push(number * 5);
});

The above worked for me, what Martin said did not mark the code challenge as correct.

const numbers = [1,2,3,4,5,6,7,8,9,10];
let times10 = [];
numbers.forEach(number => times10.push(number * 10));
